CHECK BlLLlARD-MARKER.

SPECIFICATION forming part of Letters Patent No. 308,675, dated December2, 188

Application filed June 25, 1884.

T to whom it Tll/[tj/ concern:

Be it known that I, Tnorms CLARKE J EN- KINS, of \Vellington, NewZealand, have invented a new and Improved Check Billiard- Marker, ofwhich the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved device formarking in the game of billiards, and keeping a register of the numberof games played, which device is to be known as a check billiardunarker.

The invention consists in a box provided with a hinged or sliding cover;in which two longitudinal slots are formed, behind each of which aroller is journaled, on which a series of rows of numerals are produced,each roller being provided with a shaft having a handle for revolvingthe roller the distance of one row of numerals, according as the numberof points made increases, so that the rows of numerals will successivelyshow in the slots in the cover of the box. Sliding pointers are (Nomodel.)

held on the front of the box, which point to the several numeralsshowing through the slots.

The invention further consists in a n1echanism for releasing the rollersand permitting the springs connected with the same to throw them back,so that the first rows of numerals will show through the slots.

The invention further consists in three counting-disks provided withmechanism for operating them from the two rollers above 1nentioned,which counting-disks are arranged behind a slot in the cover.

The invention also consists in various parts and details and numerouscombinations of the same, as will be fully described and set forthhereinafter.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures. 1

Fig. 3 is a face view ofthe opposite end, the cover being removed and parts being broken out andothers shown in section. Fig. 4 is a cross-sectional elevation on theline a; m,

Fig. Fig. 5 is a cross-sectional elevation on the line 3 3 Fig. 3. Fig.6 is a face view of the inner side of one of the disks for registeringthe number of games, and Fig. 7 is a face view of the cam for throwingup the pawl on the ratchet-wheels of the rollers provided with the rowsof numerals.

The boX A is provided in its front with a hinged or sliding door orcover, B, provided with two longitudinal slots, Cand O, and with twogrooves, c and c, in which grooves tenons pass, which are secured onpointers D and D, the points of which project over the upper and loweredges of the slotsOand C, respectively, the pointers being held to slideon the outer sur face of the cover 13. The slots 0 and (3 do not extendfrom one end of the cover to the other; but at one end of the cover asolid part, E, is formed, in which a slot, E, is made, which is coveredwith glass, and through which the register marking the number of gamesplayed shows.

Beneath each slot 0 and C a roller, F or F, is journaled, parallel withthe said slot, on which rollers five rows of numerals, from 0 to 99,inclusive, are arranged, the first row containing the numerals from O to19, the second from to 39, the third from to 59, the fourth from 60 to 79, and the fifth from 80 to 99, inclusive, and in the middle of thethird row the numeral is located, which is made of a different colorfrom the rest, or is arranged in such amanner that it can easily bedistinguished from the other numerals. The rollers F and F are eachprovided in their outer end with an aperture, into which short shafts Gand G, respectively, passthat is, the shaft G passes into the end of theroller F, and the shaft G into the end of the roller F. Shafts H and Hpass into the opposite ends or the rollers F F. The shafts G G arejournaled in a frame, I, projecting from the inner surface of the bottomor back of the box, and the shafts G and G are provided at their outerends with crank-handles g and g, for turning the said shafts. The shaftsare surrounded by springs and g, for throwing them back after they havebeen turned by means of the crank-handles.

On each shaft G and G an arm, G' is formed or attached, on the outer endof which a pawl,

G, is pivoted, which is pressed by a spring, G against a ratchet-wheel,J, mounted on the end of the roller F or F, whereby the roller will berevolved the distance of one tooth of the ratchet-wheel J by turning thecorresp onding shaft or spindle. The pawls G" also rest on cams K,loosely mounted on the shafts G and G, between the arms G and theratchetwheels J on the rollers. Each cam is provided with a notch, K,and against each cam a pawl, J, rests, which is acted upon by a spring,J to press it against the edge of the cam. The cams on the two shafts Gand G are connected at their lower ends by a connecting-bar, 1Q, fromwhich a pin, 7.:, passes through a slot in the lower end of an arm, L,formed on the end of a shaft, L, also journaled in the end of the box inthe same manner as the shafts G and G, which shaft L is provided at itsouter end with a handle, L

for turning it. A spring, g", acts on the shaft L, and throws it backafter it has been turned. If the player makes a certain number of pointsbetween 1 and 19, he moves the corresponding pointer, D or D, to thenumber corresponding with the number of points he has made. If thisnumber is greater than 20, he pulls down the crank-handle g or g of theroller for indieating his points, and then moves the pointer to thenumber of units above 20 required to indicate the number of points hehas made. Every time the crank-handle g or g is turned, thecorresponding pawl, G, engages with the teeth of the correspondingratchet-wheel, J, and turns the corresponding roller the distance of onetooth. If the handle is released, the spring or g 011 the shaft of thehandle that has been turned throws the handle back, and the pawl Grslides back over the teeth of the ratehet-wheel, and so on. Every timetwenty units have been made, the roller is turned to expose a new lineof figures in the slots 0 or O. A game can be played to fifty or to onehundred points, or to thirty or sixty, as may be customary, and thenumbers in the rows on the rollers can be arranged in different manners,according to the customary way of playing and marking. After a game hasbeen played and all the points counted, itis necessary to throw therollers back again, so that the first row of numbers will. show in theslot 0 or O. This is accomplished by means of springs M, held in thecircular projection h on those ends of the rollers opposite the onesprovided with the ratchet-wheels J ,whieh springs have one end securedon the inner surface of the circular proj ections,and the other endsecured on the shafts H or H of the rollers; but in order to permit thesprings to throw back the rollers, the pawls G must be disengaged byturning the shaft Lto lift the bar K connecting the cams K, whereby thecams K will be moved in such a manner as to raise the pawls G anddisengage them from the ratchetwheels J. The handle L is prevented fromswinging back too far by suitable stop-pins.

It is also necessary to provide means for antomatically registering thenumber of games played. This is accomplished by means of three rollersor disks, N, N, and N", mounted loosely on a shaft, N, next the innerends of the rollersF or F-that is, at the ends of those rollers oppositethe ones on which the ratchet wheels J are mounted. The disks N, N", andN are each provided 011 their peripheries with the numbers 0 to 9,inclusive. Each disk is provided on its outer surface with aratchetwheel, 0, and ashort distance from the ratchetwheel, 011 the diskN a disk, 1 is held rigidly on shaft N, on the outer surface ofwhichdisk a pawl, 1?, is pivoted,whieh is provided at one end with a pin, 1,adapted to pass into the notches between the teeth of the ratchet-wheelO, the disk 1? being provided with a notch, P, into which the pin P canpass, so that it will not project beyond the edge of the disk 1;.

Between the ratchet-wheel 0 and the corresponding disk, 1?, alever,Q, isloosely mounted on the shaft N, which lever is provided at one end witha pawl, Q, which is pressed against the teeth of the ratchet-wheel by aspring, Q. The opposite end of the leverQ is forked, and into the forkpasses a pin, It, projecting from a bar, R, connecting two rocking armsor levers, R, pivoted on a suitable frame on the front surface of theback of the box, which arms are pressed toward the bottom of the box bysprings R". Gains S are formed on the ends of the rollers F and F,whichcams are adapted to act on pins Son the arms It", and thus move the barR upward.

On the inner surface of each disk N and N a disk, T, is secured, onwhich a pawl-lever, T,acted on by a spring, is pivoted, which pawlleveris provided at its free end with a pin,T-, adapted to engage with theteeth of the ratchet wheel 0 of the adjoining disk,whieh pin T" alsopassesinto a notch, t, in the edge of the adjoining disk P. On the outersurface of. the disk N the lever Qis arranged between the disk 1 and theratchet-wheel O; butin the remaining disks N and N 3 the disk 1? and theratchet-wheel O are adjoining each other. Each disk Pis provided with apawl-lever, T, as described,with a notch, t, and the pin T" on the leverT, pivoted 011 the disk T on the inner surface of the first disk, N,passes into the notch Z and engages with the ratchet-teeth of the wheel0 on the second disk, N, and likewise the pin T 011 the pawl-lever T,pivoted on the disk T of the second disk, N passes through its notch 13and engages with the teeth of the ratchet-wheel O of the third disk, N.

As has been previously described, one of the shafts G or G must beturned as soon as twenty points have been made, or as soon as the numberof points has been made-fh-at is, on one of the rows of numbers on theroller F or F; but as soon as one of the rollers is turned the distanceof one row ot'numbers, the cam S 011 the corresponding roller begins toact on the pin S of the corresponding arm,

IIO

B and begins to move the same upward, thereby moving the forked end ofthe lever Q, Fig. 5, in the same direction, and thus causing the pawl Qon the opposite end of the lever Q to revolve the ratchet-wheel O on thefirst numbendisk, N, the distance of one tooth. The cams S are soconstructed and arranged that if the roller is revolved to showsuccessively the five rows of figures 011 the same the cams will, bymeans of arms It and bar It, cause the lever Q to move the ratchetwheelO the distance of two teeththat is, when the roller is turned to removethe first row of numerals from under the slot the disk N is moved thedistance of one number. WVhen the roller is turned to move the secondrow of numerals from under the slot, the disk N is not moved. 1f theroller is turned the third time, removing the third row of numerals fromunder the slot, the disk N is again moved one number, and when theroller is turned the fourth time the disk N is not moved. If, then, thehandle L is turned, it releases the roller and permits it to fly back,and the springs R throw the rods R and the eonnecting-bar downward,ready for another registration. After the disk N has made nine-tenths ofa revolution, the pin T" on the pawl-lever T of the disk T on the innersurface of the disk N engages with a tooth of the wheel 0 of the seconddisk, N and revolves the same the distance of one tooth. After thesecond disk, N has made nine-tenths ofa revolution, the third disk, N,is moved in a like manner, and so on. The disk N is successively movedthe distance of ten teeth. and during that time the pin T on the disk Ton the inner surface of the disk N rests on the edge of tliedisk P onthe disk N but after the disk N has been revolved the distance of nineteeth the pin T of the disk T drops into the notch t of the disk P onthe disk N", thus permitting the pin T to engage withthe teeth of theratchet-wheel O on the second disk, N, thus revolving the said disk thedistance of one tooth; but as soon as the said movement has been made bythe disk N the pin T of the disk N slides up on the spring i on the endof the pawl-lever P of the disk P, opposite the one provided with thepin I. As the end provided with the pin P is pressed out ward by a toothof the ratchet-wheel O of the disk N", the spring fis pressed down topermit the pin T to pass on it. As soon as the disk N has been revolvedthe distance of one tooth, the pin P on the end of the lever P of thedisk P on the disk N snaps back into the notch P, thereby raising thespring t and the pin T on the lever T of the disk N, thus enabling thesaid pin T to travel on the edge of the disk P of the adjoining disk,N".

In order to understand the above operation, it must be kept in mind thatthe disks P are all rigidly mounted on the shaft N. The ratchet-wheels Oare connected with the disks N, N", and N on one side and the disks T onthe opposite side, the disks N, N, and N, the

ratchet-wheels O, and the disks T being loosely mounted on the shaft N.

One of the special features of my machine is that as soon as one of theshafts G or G is turned the disk N is moved the distance of one number,thus making it impossible for a person to play more than twenty pointswithout registering a game, for a person might well make twenty points,and then run out on a single run without requiring any furtherregistering of points. Then no game would be registered if the cams Swere not so constructed as to move the number disks atthe first movement of the roller F or 1*".

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is
